Two new phoxocephalids (Crustacea: Amphipoda: Phoxocephalidae) from the south-west Atlantic

A new genus and species, Parafoxiphalus longicarpus, and a new species, Metharpinia protuberantis belonging to the family Phoxocephalidae, are described from the Argentine Sea. Both taxa were collected from sandy substrata in the intertidal and subtidal regions. Parafoxiphalus longicarpus is related to Foxiphalus Barnard, 1979 and they share many characters, most of them in plesiomorphic condition. Metharpinia protuberantis is an intermediate species between Metharpinia Schellenberg, 1931 and Microphoxus Barnard, 1960, and its assignation to the first genus is discussed.     

Further new species within the freshwater amphipod genus Paramelita (Crangonyctoidea: Paramelitidae) from South Africa

Four new species within the crangonyctoid amphipod genus Paramelita are described from material collected from small streams in the southwestern Cape, South Africa. Two of the species are large, with robust second antennae which exceed the first in length, especially in adult males. The third species is recognized by its slender pereopods and its densely setose second antennae, and the fourth by its small size and relatively short, slender, unmodified second antennae. All of these species have an unmodified pereopod 3, and lack teeth, spines, ridges or lobes on antenna 2, features common to many of the known Paramelita species. Morphological similarities between the four new species and 19 previously known species of Paramelita are discussed.     

First record of the genus Koreanurina Najt and Weiner (Collembola: Neanuridae: Pseudachorutinae) from China,with description of two new species from Changbai mountain

The genus Koreanurina Najt and Weiner, 1992 is recorded for the first time from China. It is redefined and its similarity with the subfamily Caputanurininae is stressed. Two species are described from Changbai Mountain in North-East China: Koreanurina weinerae sp. nov. and K. alba sp. nov. The first species differs from the other species of the genus, mostly by its post-antennal organ located on the lateral edge of head (versus dorsolaterally), its central plate on head wider and the presence of only 1 + 1 chaetae on Th I (versus 2–3 + 2–3). K. alba sp. nov. differs from the other species of the genus mostly by the absence of body pigment, and the presence of only 1 + 1 chaetae posteriorly to the furcal rest (versus 2 + 2).

A review of the genus Scyracepon Tattersall, 1905 (Crustacea: Isopoda: Bopyridae), with description of a new species from China

The parasitic isopod genus Scyracepon Tattersall, 1905 is recorded from China for the first time, and a new species, Scyracepon distincta, is described from the host Jonas distinctus (Brachyura: Corystidae). Females of the new species can be distinguished from those of the other six species of Scyracepon by their subequal mid-dorsal projections on pereomeres 6 and 7 (lacking on other pereomeres) and pleonal segments with medial but not lateral fusion. Males of the new species have the first two pleomeres free, pleomeres 3–5 fused, and bear midventral tubercles on all pereomeres and the first pleomere. This is the first record of any species of Corystidae bearing parasitic isopods. Remarks on, and a key to, the seven known species of Scyracepon are provided.     

First record of the genus Atlantistylis Reyss, 1975 (Crustacea: Cumacea) from the North Atlantic,with the description of a new species

A new species of the genus Atlantistylis Reyss, (Diastylidae) is described from the Atlantic Frontier Margin (North‐East Atlantic). This is the first record of the genus Atlantistylis from the North Atlantic. The new species Atlantistylis borealis can be recognized by the presence of spines on the frontal and lateral lobes of the carapace combined with their absence on the pereon and pleon; the first pereopods are very long. The small telson with two small apical acuminate setae and the absence of pleopods in the male are characteristic of the genus.     

News from a small island – first record of a freshwater shrimp (Decapoda,Atyidae, Caridina) from Peleng,Banggai Islands,Indonesia

The Indonesian island Sulawesi is well known for its fascinating fauna. Among the atyid and palaemonid freshwater shrimps described from Sulawesi are also a number of endemic species. In contrast, freshwater shrimps have never been reported from the nearby and smaller Peleng Island. Here we describe Caridina thomasi sp. nov. as a first record of an atyid freshwater shrimp from Peleng and compare it with atyids from Sulawesi and other localities. The new species is probably endemic to the island and shows some characters never described in the genus Caridina before. However, a molecular phylogeny of atyid shrimps from the Indo‐West Pacific based on mitochondrial DNA (16S) places C. thomasi within a clade of typical species of Caridina. We tentatively assign the new species to the genus Caridina and discuss the possibility of future changes in the classification of species in this genus.     

Considerations about the genus Pentoniscus Richardson, 1913 (Crustacea: Isopoda: Oniscidea) with description of a new species

The status of the neotropical genus Pentoniscus Richardson, 1913 is reconsidered and a diagnosis of this genus is given. It is shown that Pentoniscus Richardson, 1913 is a valid genus and not a synonym of Philoscia Latreille, 1804 as discussed by Schultz (1968). The type species, Pentoniscus pruinosus Richardson, 1913 is redescribed and for the first time figured in detail. A new species of Pentoniscus Richardson, 1913 is described from Costa Rica, Central America, which differs remarkably from its congeners in being unpigmented and blind.     

Terrapotamon gen. nov., a new genus of freshwater crabs from Malaysia and Thailand,with description of a new species,Terrapotamon aipooae sp. nov. (Crustacea: Decapoda: Brachyura: Potamidae)

A new genus, Terrapotamon gen. nov., is established to accomodate two species of freshwater crabs, Potamon abbotti Rathbun, 1898 from southern Thailand, and a new species, Terrapotamon aipooae sp. nov. from West Malaysia. Members of this genus are characterized by their inflated carapaces, very acutely triangular external orbital angles, and structure of their first male gonopods.     

A survey of the genus Geometra Linnaeus (Lepidoptera,Geometridae, Geometrinae)

The type genus of the family Geometridae, Geometra Linnaeus, is reviewed. In addition to the 16 species known worldwide, two new species are described: Geometra neovalida sp. nov. from China, and Geometra burmensis sp. nov. from Burma (Myanmar). All the known species are redescribed. Genitalia of all species are described and illustrated, most for the first time. Generic characters based on all species are summarized. The monophyly of the genus and its relationship with allied genera are reviewed and discussed in detail. Most species fall into two species groups, named the papilionaria and smaragdus groups, on the basis of the morphology of the male genitalia. Biological information is provided where available. Illustrations of moths and genitalia are presented.     

Notes on the Amazonian genus Hyogonia China (Hemiptera: Cicadellidae: Proconiini) with a description of a new species

Oncometopia batesi Distant, described from northern Brazil (State unknown), is transferred to the genus Hyogonia China. Hyogonia brasiliana sp. nov. is described from Northern Brazil, Pará State, the easternmost record of the genus. The new species is easily distinguished from all other Hyogonia species by the following combination of characters: (1) pronotum without distinct transverse contrasting band; (2) pygofer with short processes that do not attain its apex; (3) both pairs of aedeagal atrial processes divergent and short, never longer than aedeagal shaft; and (4) aedeagal caudal pair of atrial processes with bases close to each other, appearing as a single bifurcated robust process. Hyogonia batesi and H. brasiliana, together with an unidentified female from Acre State, represent the first authentic records of the genus Hyogonia from Brazil. Previous records of H. reticulata (Melichar) and H. youngi Emmrich and Lauterer from Brazil are erroneous as their recorded locality ‘Cumbase’ is most probably located in Peru (San Martín Department). Other new records from countries and major federal divisions are noted as follows: the genus Hyogonia (unidentified species) from Barinas State (Venezuela); H. batesi from Ecuador (Orellana Province); H. reticulata from Amazonas and Junín Departments (Peru); and H. youngi from Ecuador (Napo Province). A key to the known species of Hyogonia is provided.     

A review of the genus Parapenaeonella (Isopoda: Bopyridae: Orbioninae), with description of a new species from Chinese waters and synonymy of Parapenaeonella lamellata Bourdon, 1979

We report the first record of the parasitic isopod genus Parapenaeonella Shiino, 1949 from China. Two species are reported infesting penaeid shrimps; one is new to science, and another is a new record from China. The new species differs from Parapenaeonella distincta Shiino, 1949 in its widely open brood pouch, small biramous pleopods, simple barbula, and its male with midventral tubercle on the first pleomere. Information on the high morphological variability of males of P. distincta Shiino, 1949 and its new synonym, Parapenaeonella lamellata Bourdon, 1979, is presented. http://www.zoobank.org/urn:lsid:zoobank.org:pub:B3E0879E-EF5E-42EA-B062-3A6361DA1B5D     

Redescriptions of two termites from Burmese amber

Summary

Danothrips Bhatti 1971 is revised and its relations with Chaetanaphothrips Priesner are discussed. The genus is redefined in view of the increased number of species within the genus, and a key is provided to distinguish the species. Six species are included: setifer Bhatti 1971 theifolii (Karny 1921), theivorus (Karny 1921), trifasciatus Sakimura 1975, and two new species, alis and moundi. The range of distribution of trifasciatus, originally described from Hawaii, is considerably extended by its new findings from the Lesser Antilles (St. Vincent Island) and Indonesia (Andalas).     

Stenothoidae (Crustacea: Amphipoda) of hydrothermal vents and surroundings on the Mid‐Atlantic Ridge,Azores Triple Junction zone

Four new species of Stenothoidae were collected from the Azores Triple Junction zone during different French cruises on the Mid‐Atlantic Ridge. One of the species belongs to the genus Torometopa (T. saldanhae) and is the first record of this genus in the Atlantic Ocean. The three other species belong to the genus Stenothoe (S. divae, S. marvela, and S. menezgweni). It is not possible to determine from morphological and ecological characters whether these amphipod species are endemic to hydrothermal systems or are bathyal species that may be found away from vent sites.     

Oribatid mites of Liebstadia (Acari: Oribatida: Scheloribatidae) from Mongolia,with notes on taxonomy of the genus

Three new species of oribatid mites belonging to the genus Liebstadia are described from Mongolia. The new species are characterized by the poorly developed pteromorphae; the club-shaped head of the sensilli; the absence of the dorsosejugal suture; the dorso-ventral thickness, and the length and arrangement of notogastral setae. In addition, L. similis (Michael, 1888) is redescribed and recorded for the first time in Mongolia. Protoribates serratomarginatus Mahunka, 1983 is synonymized with L. similis. A key to the known species of the genus Liebstadia is given.     

Four new freshwater gobies of the genus Rhinogobius (Teleostei: Gobiidae) from northern Vietnam

Four new freshwater gobies of the genus Rhinogobius Gill, were collected from the river running into the Gulf of Tonkin in northern Vietnam. They are Rhinogobius boa new species, Rhinogobius variolatus new species, Rhinogobius virgigena new species and Rhinogobius sulcatus new species. These four new species can be distinguished from other congeneric species by a combination of characters such as the meristic features, shape of body, shape of first dorsal fin and coloration pattern.     

Ooencyrtus marcelloi sp. nov. (Hymenoptera: Encyrtidae), an egg parasitoid of Heliconiini (Lepidoptera: Nymphalidae: Heliconiinae) on passion vines (Malpighiales: Passifloraceae) in Central America

A new species belonging to the genus Ooencyrtus Ashmead is described. Ooencyrtus marcelloi sp. nov. has been reared from eggs of Heliconiini (Lepidoptera: Nymphalidae, Heliconiinae) collected in Panama on Passiflora spp. The new species is compared with its closest Ooencyrtus species, i.e. O. caligo Noyes, O. neustriae Mercet, O. flavipes (Timberlake), O. camerounensis (Risbec), O. endymion Huang and Noyes and Ooencyrtus sp. “undet. C.” (from India). This represents the second record of Ooencyrtus from Heliconinae and the first record of this genus from Panama.
